On the cover Fallon is clothed from the waist up in a jacket, shirt and tie, but his bottom is stripped and slightly covered by a sticker indicating the album’s release date.

“I don’t even remember taking this photo at all,” Fallon joked on the show, holding up the album cover. “It’s just a guy relaxing at home. He has a nice glass of wine…Started listening to the album and his pants blew off. “

Fallon pointed out that if you buy the album, it doesn’t come with the strategically placed sticker.

“I don’t know if this is my butt or a stunt butt. There’s rumors going around that it’s like the ‘Mona Lisa’ of album covers,” Fallon added.

The album features original and parody songs as well as humorous jams with top artists including Justin Timberlake, Paul McCartney, Eddie Vedder and Bruce Springsteen.
